The inner ear (internal ear, auris interna) is the innermost part of the vertebrate ear. In vertebrates , the inner ear is mainly responsible for sound detection and balance. [ 1 ] In mammals , it consists of the bony labyrinth , a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts: [ 2 ]
Tonotopy in the auditory system begins at the cochlea, the small snail-like structure in the inner ear that sends information about sound to the brain. Different regions of the basilar membrane in the organ of Corti , the sound-sensitive portion of the cochlea, vibrate at different sinusoidal frequencies due to variations in thickness and width ...
The inner ear consists of the cochlea, which is a spiral-shaped, fluid-filled tube. It is divided lengthwise by the organ of Corti , which is the main organ of mechanical to neural transduction . Inside the organ of Corti is the basilar membrane , a structure that vibrates when waves from the middle ear propagate through the cochlear fluid ...
The cochlea is the part of the inner ear involved in hearing. It is a spiral-shaped cavity in the bony labyrinth , in humans making 2.75 turns around its axis, the modiolus . [ 2 ] [ 3 ] A core component of the cochlea is the organ of Corti , the sensory organ of hearing, which is distributed along the partition separating the fluid chambers in ...
The human ear is made up of three areas: the outer, middle and inner ear. Within the inner ear sits the cochlea. The cochlea is a snail-shaped formation that enables sound transmission via a sensorineural route, rather than through a conductive pathway. [11] The cochlea is a complex structure, consisting of three layers of fluid.
The inner ear consists of the cochlea and several non-auditory structures. The cochlea has three fluid-filled sections (i.e. the scala media, scala tympani and scala vestibuli) , and supports a fluid wave driven by pressure across the basilar membrane separating two of the sections.
For example, very curvy ear canals, narrow ear canals, or surgical ears are more prone to earwax buildup. When wax builds up, it causes muffled hearing, tinnitus, or aural fullness (plugged-up ...
The Outer ear consists of the pinna or auricle (visible parts including ear lobes and concha), and the auditory meatus (the passageway for sound). The fundamental function of this part of the ear is to gather sound energy and deliver it to the eardrum. Resonances of the external ear selectively boost sound pressure with frequency in the range 2 ...
